Overview

Atlantic Power is an independent power producer that owns power generation assets in nine states in the United States and two provinces in Canada. The generation projects sell electricity and steam to investment-grade utilities and other creditworthy large customers predominantly under long term Power Purchase Agreements (PPAs) that have expiration dates ranging from 2019 to 2037. The Company seeks to minimize its exposure to commodity prices through provisions in the contracts, fuel supply agreements and hedging arrangements. The projects are diversified by geography, fuel type, technology, dispatch profile and offtaker (customer). The majority of the projects in operation are 100% owned and directly operated and maintained by the Company. The Company has expertise in operating most fuel types, including gas, hydro, and biomass, and it owns a 40% interest in one coal project.

Atlantic Power shares trade on the New York Stock Exchange under the symbol AT and on the Toronto Stock Exchange under the symbol ATP.
